--DESCRIPTION: stamina script by smallg
--DESCRIPTION: player starts with [StartingStamina=50] current stamina 
--DESCRIPTION: and a limit of [MaxStamina=100]
--DESCRIPTION: stamina drains at a rate of [DrainRate#=0.1] while running
--DESCRIPTION: [JumpStaminaDrain#=3] - (if you don't want jump to be disabled set jump stamina drain to 0)
--DESCRIPTION: while player is walking stamina will recover at a rate of [RecoverRateWalking#=0.01] 
--DESCRIPTION: if player stops completely stamina recovers at rate of [RecoverRateStopped#=0.1]
--DESCRIPTION: after running out of stamina you can't sprint again until you recover at least [MinRecovery=5] stamina
--DESCRIPTION: Position of the stamina display text on screen
--DESCRIPTION: [TextPosX=92(0,100)]
--DESCRIPTION: [TextPosY=93(0,100)]
--DESCRIPTION: [TextSize=4(1,5)]
--DESCRIPTION: plays <Sound0> when out of stamina and <Sound1> when stamina is back above <MinRecovery>
